NCT04708470

A Phase I/II Study of Combination Immunotherapy for Advanced Cancers Including HPV-Associated Malignancies, Small Bowel, and Colon Cancers

Background: Often, metastatic human papillomavirus (HPV) associated cancers cannot be cured. They also do not respond well to treatment. Some forms of colon cancer also have poor responses to treatment. Researchers want to see if a new drug treatment can help people with these types of cancers. Objective: To find a safe dose of entinostat in combination with PDS01ADC and bintrafusp alfa and to see if this treatment will cause tumors to shrink. Eligibility: Adults ages 18 and older who have cervical, oropharyngeal, anal, vulvar, vaginal, penile, squamous cell rectal, or another cancer that may be associated with HPV infection or microsatellite stable small bowel or colorectal cancer. Design: Participants will be screened with a medical history and physical exam. Their ability to do daily activities will be assessed. They may have imaging scans of the brain and/or chest, abdomen, and pelvis. They may have nuclear bone scans. They will have an electrocardiogram to test heart function. They will have blood and urine tests. They may have a tumor biopsy. Participants with skin lesions may have them photographed. Some screening tests will be repeated during the study. Treatment will be done in 28-day cycles. Participants will get bintrafusp alfa through an intravenous catheter every 2 weeks. They will get PDS01ADC as an injection under the skin every 4 weeks. They will take entinostat by mouth once a week. They will complete a medicine diary. Participants will get treatment for 2 years. They will have 1-2 follow-up visits in the 30 days after treatment ends. Then they will be contacted every 6 months to check on their health.

Irreversible Electroporation (IRE) for Treating Recurrent Pelvic Tumors (PELFIRE Study)

The goal of this single-center observational cohort study, based on a registry combining retrospectively and prospectively collected data, is to investigate the short- and long-term effects of irreversible electroporation (IRE) in men and women over the age of 18 who receive IRE for recurrence of pelvic tumors not suitable for other local treatment options such as surgery, thermal ablation, and radiotherapy. The main question it aims to answer is whether IRE is safe in this population, and secondarily, whether it is effective in controlling local tumor recurrence.

Ovarian-Sparing Adaptive Radiotherapy in Young Adult Women

Female patients with early onset (\<50 years old) pelvic malignancies such as uterine and rectal cancers are rising in incidence, which often requires pelvic radiation; many of these patients are premenopausal and at a high risk of premature ovarian failure from radiotherapy. Premature ovarian failure carries significant cardiac, musculoskeletal, sexual, and psychosocial morbidity. Ovarian transposition carries variable success rates, is not readily accessible to the general population, and can still be at risk of clinically significant radiotherapy doses. There is an unmet need for innovative techniques to protect ovarian function.

CASCADE: Testing for Safety and Immune Effects of PDS0101, an Anti-HPV Therapy, Among People Living With HIV

This study is testing the immunotherapeutic agent, PDS0101, in adults living with HIV who are also infected with human papillomavirus (HPV) type 16. The purpose of the study is to learn whether PDS0101 is safe and whether it can help the body's immune system respond to HPV 16. Researchers will enroll 27 adults, at least 25 years of age, who have been receiving antiretroviral therapy (ART) for at least 12 months, have a cluster of differentiation 4 (CD4) cell count of at least 200 cells/mm³, and have an HIV viral load below 200 copies/mL. All participants must have HPV 16 detected in the cervix, vagina, or anus. Some participants will have high-grade squamous intraepithelial lesions (HSIL), a condition that can lead to cancer. At least 10 participants will have cervical HSIL, and at least 10 will have anal HSIL. Participants with both cervical and anal HSIL will count in both groups. Others may have HPV 16 without HSIL. This is a single-arm, open-label trial, which means that all participants will receive the same treatment, and both the investigators and the participants will know what the treatment is. Each participant will receive three doses of PDS0101. Participants who receive at least one dose will be included in the study's main safety analysis. If a participant does not receive all three doses and does not experience a serious side effect related to PDS0101 (defined as a Grade 3 or higher toxicity), that participant may be replaced to make sure that 27 participants either complete the full vaccination schedule or experience a primary safety event. Participants who do have a qualifying safety event will not be replaced. Even if someone stops the study early, their data will still be included in the final analysis. The main goals of this study are to evaluate the safety of PDS0101 and to measure the immune response it produces. The safety evaluation includes monitoring for serious or unexpected side effects, especially those that are Grade 3 or higher in severity. The immune response will be assessed by looking at how the body's T cells respond to HPV 16 after PDS0101 administration. The total time a participant is involved in the study includes the PDS0101 administration period and several follow-up visits, which may take place over the course of several months. This research may help inform future strategies for preventing or treating HPV-related disease in people living with HIV.

HPV Vaccine PRGN-2009 Alone or in Combination With Anti-PDL1/TGF-Beta Trap (M7824) in Subjects With HPV Associated Cancers

Background: For some cancers associated with human papillomavirus (HPV), standard treatments are not helpful. Researchers want to see if a vaccine for HPV combined with a drug called M7824 (MSB0011359C) has a better effect on these cancers than when they work alone. Objective: To find a safe dose of HPV vaccine alone or combined with M7824. Also, to test if either HPV vaccine alone or combined with M7824 causes a better immune response. Eligibility: People ages 18 and older with locally advanced or metastatic HPV associated cancer (Phase I) or stage II or III p16-positive oropharyngeal cancer (Phase II) Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests Possible photos of skin lesions Computed tomography (CT), magnetic resonance imaging (MRI), or nuclear bone scan: Participants will lie in a machine that takes pictures of the body. For the CT scan, they may have a contrast agent injected into a vein. Participants may have up to 2 tumor biopsies. For participants in Phase II, this may be performed with a thin tube placed through the nose into the airway. Participants will receive the HPV vaccine alone or with M7824. For participants on the Phase II, they will receive two doses of HPV vaccine under the skin either alone or with M7824 as an infusion spaced two weeks apart. This will be done prior to their planned chemoradiation or surgery. For participants on the Phase I, they will get the HPV vaccine injected under the skin 2 to 3 times in the first month. Then they will have a booster every 4 weeks. They will receive M7824 as an infusion into a vein every 2 weeks. Treatment will last up to 1 year. After they stop treatment, participants will have a visit within 4 weeks. They will then be contacted for long-term follow-up every year, for the rest of their lives. ...

ctHPVDNA Response-Adapted Chemoradiation +/- Retifanlimab Treatment in Locally-Advanced Anal Cancer

This study is for people who have anal cancer and have not yet had treatment. The regular treatment for people who have anal cancer is chemoradiation therapy (CRT). CRT is when chemotherapy and radiation therapy are given at the same time. Studies show that CRT works well to treat anal cancer and prevents many people from needing surgery which may require a colostomy bag. Doctors know that CRT is an effective way to treat anal cancer. But, they are doing studies to find out how much dose of radiation and chemotherapy should be given during the CRT. Higher doses of chemotherapy and radiation could increase the risk of side effects, but lowering the dose of chemoradiation has the risk of not being as effective to treat the cancer. One way to predict whether participants need higher or lower doses of radiation therapy is to do a blood test called ctDNA (circulating tumor DNA) to test for the presence of human papillomavirus (HPV). This test is done at certain times while participants are getting CRT. This has been shown to be a marker for the presence of anal cancer. In this study, doctors will tailor lower versus higher doses of CRT based on the tumor response that is measured by ctDNA. The purpose of this study is to see if customizing the dose of chemoradiation based on the amount of ctDNA will increase survival in participants with anal cancer and/or decrease the risk of side effects. Some participants in this study whose cancer does not respond as well to the CRT may have the opportunity to receive a drug called Retifanlimab that stimulates the body's immune system. Retifanlimab is approved by the Federal Drug Administration (FDA) for treating anal cancer that is recurrent or metastatic since there is proven benefit in these situations.

Distance-Based Exercise to Preserve Function and Prevent Disability

This clinical trial studies whether an exercise program can be successfully delivered to patients receiving treatment for cancer through virtual sessions and allow patients to exercise in their own home. Treatments for cancer can cause side effects such as fatigue and loss of strength. These side effects can make it difficult to work, take care of family, and do other things the patient wants to do. Preliminary research shows that exercise can help prevent some of these side effects, but it can be more difficult to start an exercise program when a patient is receiving cancer treatment. The exercise program in this study is delivered through telehealth (TH) video calls. The TH sessions are delivered by trained staff that supervise resistance exercises. The trained staff also provide guidance to the patient on completing unsupervised aerobic sessions on their own. This may be a successful way to deliver an exercise program and make it easier for cancer patients to exercise in their own home during treatment.

Combination Immunotherapy in Subjects With Advanced HPV Associated Malignancies

Background: More than 30,000 cases of human papillomavirus (HPV) associated cancers occur annually in the United States. When these cancers spread, they do not respond well to standard treatments and are often incurable. Researchers want to see if a mix of drugs can help. Objective: To learn if a mix of immunotherapy drugs can shrink tumors in people with HPV associated cancers. Eligibility: People ages 18 and older with locally advanced or metastatic HPV associated cancer, such as cervical cancers; cyclin-dependent kinase inhibitor 2A (P16+) oropharyngeal cancers; anal cancers; vulvar, vaginal, penile, and squamous cell rectal cancers; or other locally advanced or metastatic solid tumors (e.g., lung, esophagus) that are known HPV+ cancers Design: Participants will be screened with: * medical history * disease confirmation (or tumor biopsy) * physical exam * body scans (computed tomography (CT), magnetic resonance imaging (MRI), and/or nuclear) * blood tests * electrocardiogram (to measure the electrical activity of the heart) * urine tests. Participants will get PDS0101 injected under the skin every 4 weeks for 6 doses. Then they will get it every 3 months for 2 doses. Participants will get M7824 (MSB0011395C) by intravenous infusion every 2 weeks. For this, a needle is inserted into a vein. The drug is given over a 1-hour period. Participants will get NHS-IL12 injected under the skin every 4 weeks. Participants will get the study drugs for up to 1 year. They will visit the NIH every 2 weeks. They will repeat the screening tests during the study. About 28 days after treatment ends, participants will have a follow-up visit or telephone call. Then they will be contacted every 3 months for 1 year, and then every 6 months after that, for the rest of their life. Patients with cervical cancer with prior pelvic radiation and boost brachytherapy will be enrolled in a separate cohort to evaluate safety and preliminary evidence of efficacy...

COQ10 and Vitamin E for Off-Target Radiation Toxicity

The goal of this supportive care study is to learn if high-dose Vitamin E and CoQ10 in combination can reduce the negative sub-acute and chronic side effects of radiation to the pelvis in adults treated for prostate, uterine, cervical, or anal cancer. The main questions it aims to answer are: * Is taking high doses of Vitamin E (dl-α-tocopherol acetate, 900mg) and CoQ10 (ubidecarenone, 200 mg) each day safe and tolerable? * Does a 90-day course of vitamin supplementation with high-dose Vitamin E and CoQ10 reduce the incidence and severity of late radiation-associated toxicities? * Does high-dose vitamin supplementation with Vitamin E and CoQ10 improve patient reported measure of quality of life? * Does high-dose vitamin supplementation with Vitamin E and CoQ10 change the trajectory of recovery after radiation therapy? * Is there evidence that suggests high-dose vitamin supplementation with Vitamin E and CoQ10 impairs oncologic outcomes? * Can longitudinal biomarkers of oxidative stress be correlated with Vitamin E and CoQ10 concentrations or radiation-associated toxicity? * Will subjects adhere to the vitamin administration schedule? * Are there demographic differences in systemic exposure to the vitamins? * Are there differences in toxicity outcomes across tumor types or radiation dose fractionation schemes? Participants will be asked to: * Take Vitamin E and CoQ10 every day for 90 days by mouth. * Fill out quality of life questionnaires to assess treatment impacts. * Come for clinic visits every 2-4 weeks for around 4 months, then every 3-6 months for around 2 years. * Have blood draws more frequently than standard-of-care for clinical laboratory examinations and the collection of research samples. * Undergo Computed Tomography (CT) imaging of the chest, abdomen, and pelvis more frequently than standard of care. * Agree to lifestyle changes that ensure adequate vitamin absorption including intermittent abstinence from alcoholic beverages.

E7 T-cell Receptor (TCR) -T Cell Induction Therapy for Locoregionally Advanced HPV-associated Cancers

The goal of this study is to determine the feasibility of administration of a single dose of E7 TCR-T cells as induction therapy prior to definitive treatment (chemoradiation or surgery) of locoregionally advanced HPV-associated cancers. The intent of E7 TCR-T cell treatment is to shrink or eliminate tumors and thereby facilitate definitive therapy and increase overall survival. This study seeks to determine 1) if E7 TCR-T cells can be administered without undue delay in definitive treatment, 2) the tumor response rate to E7 TCR-T cell treatment, and 3) the disease-free survival rate at 2 and 5 years. Participants will undergo an apheresis procedure to obtain T cells that will be genetically engineered to generate E7 TCR-T cells. They will receive a conditioning regimen, a single infusion of their own E7 TCR-T cells, and adjuvant aldesleukin. Participants will follow up to assess safety and determine tumor response and will return to their primary oncology team for definitive therapy.

Blood Biomarkers Based Screening for HPV-driven OPC

The objective of our study is to demonstrate that it is possible to detect and treat human papilloma virus (HPV)-related oropharyngeal cancers (OPC) early using simple blood tests. The success of this strategy will be evaluated by the number of participants positive for both HPV16-E6 serology and HPV circulating tumor DNA (ctDNA) whose early management has allowed the detection of a cancerous lesion and/or whose HPV ctDNA results have normalized after surgical intervention. If this study is conclusive, it could pave the way for the implementation of a national screening strategy for HPV-related OPC.

EQUITY GI: A Prospective Study to Enhance Quality, Inclusivity, and Trial Participation in Black Patients With Gastrointestinal Cancer.

This research study is being conducted to improve the quality of care of participants who have a diagnosis of gastrointestinal cancer (anal, colon, rectal, esophageal, stomach, small bowel, appendix, pancreas, gall bladder, liver, neuroendocrine tumor of gastrointestinal origin). This study has 3 components as follows- 1. Ensuring appropriate biomarker testing and evidence-based care: Biomarkers are molecules in the tumor or blood that indicate normal or abnormal processes in participant's body and may indicate an underlying condition or disease. Various molecules, such as DNA (genes), proteins, or hormones, can serve as biomarkers since they all indicate something about participant's health. Biomarker testing can also help choose participant's treatment. Additionally, a tumor board will be conducted periodically to provide treatment recommendations to participant's treating physician. Participants will receive standard-of-care treatment if participant enroll in this study. Participant will not receive any experimental treatment. 2. Assistance with clinical trial enrollment. The study team will help participants enroll in a clinical trial appropriate for participant's condition. However, enrolling in a clinical trial is totally up to the participant. 3. Health literacy: The study team will provide information relevant to participant's diagnosis to enrich participant's understanding of participant's condition and treatment. Investigator will provide questionnaires to assess participant's understanding before and after participant's have been provided with educational/informational material appropriate for participant's diagnosis.

Screening for Anal Cancer in Men Who Have Sex With Men Using Pre-Exposure Prophylaxis

This study aims to learn more about anal cancer risk in men who have sex with men (MSM) who are using Pre-Exposure Prophylaxis (PrEP) to prevent HIV. Specifically, we want to check how common High-Grade Squamous Intraepithelial Lesions (HSIL) are in this group, how well anal swabs can screen for these lesions, and how having HSIL affects their quality of life. We'll also test if DNA methylation testing can give us extra information about the lesions. The main questions the study aims to answer are: * How common are HSIL in MSM using PrEP? * How accurate are anal swabs for detecting HSIL in this group? * How does having HSIL affect the quality of life of MSM using PrEP? * Can DNA methylation testing help improve our understanding of HSIL in these individuals? Participants will: * Answer questions about their health and quality of life. * Have an anal smear collected for testing. * Undergo High-Resolution Anoscopy (HRA) to check for HSIL and get a biopsy if deemed necessary.

Intrafractional Vaginal Dilation in Anal Cancer Patients Undergoing Pelvic Radiotherapy

A commercially available vaginal dilator set will be used as measuring device. The grading of vaginal stenosis will be determined as difference of the diameter of vaginal dilator to the baseline. A reduction of the diameter of \<20% is defined as vaginal stenosis Grade 1, a reduction of 20-35% as Grade 2, a reduction of \>35-49% as Grade 3 and a reduction \>/=50% as Grade 4. The investigators hypothesize that the rate of vaginal stenosis Grade 1 or higher 12 months after radiotherapy is lower in the group using extended vaginal dilation during radiotherapy (Arm A). Rates of vaginal stenosis of 50% have been observed in previous patient collectives and the investigators hypothesize that a reduction to 25% is possible in the experimental group.
